- DR r-EQUALIZER.

To all whom it may concern:

Be it known that I, 0111s T. I-IoY'r, a citi zen of the United States,residing at Good Hope in the county of McDonough and State of Illinois,have invented a new and useful Draft-Equalizer; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a new and useful draft equalizer.

An object of the invention is to provide an improved equalizer, which issimple, durable and inexpensive in construction, and one which willquickly equalize the draft at all points.

One of the features of the invention is the provision of a mainequalizer beam having a series of openings, in which links are connectedhaving rollers over which a draft chain passes, which chain also passesover rollers of links connected to swingletrees, thereby affording adraft equalizer, so that when a greater part of the load or draft isthrown upon either one of the outer animals it will be quickly returnedupon the other two animals.

In practical fields the details of construction may necessitatealterations, to which the patentee is entitled, provided the alterationsfall within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a plan view of the eqealizer, showing theswingletrees attached. Fig. 2 is a plan view showing the greater part ofthe draft or load on one of the outer animals. Fig. 3 is a plan Viewshowing the position of the other two swingletrees, after the load ordraft has been quickly returned back to the other two animals. Fig. 4 isa detail perspective view of one end of the evener beam, showing thelinks 9 and a portion of the chain 19 passing thereover.

Referring more particularly to the drawings, 1 designates the mainequalizer'beam having three openings 2, 3 and 4, through which the bolts5 and 6 extend, which bolts also pass through the links 7 and 8, and 9and 10. The bolt 5 also passes through a clevis 11, which is designed tobe connected to a wagon or the like. Arranged between the links 7 and 8are groove rollers 12 mounted upon the bolts 13, while arranged betweenthe links 10 is a roller 13, also mounted upon the bolts 14, whereasbetween the links 9 roller 16 is arranged on a bolt 17. Passing over therollers of the links 7 and 8, and 9 and 10 is a chain 19, detachablyconnected at 20 at each end of the equal- Specification of LettersPatent.

izing beam. Swingletrees 21, 22 and 23 are provided, to which the links24: are connected by the bolts 25. The bolts 26 also pass through thelinks 24, which bolts 26 act as journal pins for the rollers 27, overwhich the chain also passes.

Referring to Fig. 1 it will be seen that the draft is equallydistributed, while in Fig. 2 the greater part of the draft or load hasbeen shifted to one of the outer swingletrees, in which case the outerswingletree moves laterally in the direction of the arrow at andforwardly, at the same time the equalizing beam assumes an angle. Justso soon as-these actions occur, the equalizing beam instantly assumingsuch angles as shown in Fig. 2, the greater part of the load or draft isreturned or transferred back to the other two swingletrees, therebycausing the parts of the equalizer to assume the position as shown inFig. 3. These actions are more or less quickly performed, owing to theprovision of the links of the equalizing beam and the openings 2, 3 and4, thereby in this manner an eflicient, durable and practical draftequalizer is afforded.

The invention having been set forth, what is claimed as new and usefulis A draft equalizer comprising a beam constituting an evener and havinga slot adj acent each end and a substantially centrally disposed slot, aclevis connection connected to said centrally disposed slot and designedfor connection to a vehicle, a multiplicity of links arranged in pairs,two pair being pivotally joined and having pivotal connections at theirjoined ends with said clevis in the centrally disposed slot, whileanother pair has a bolt connection with each end slot, said links havingrollers between their free ends, a draft chain having its ends connectedto opposite ends of the evener beam, the chain intermediate such endconnections passing over the roll ers of said links and forming loops,one loop being beyond the roller of each pair of end links, and a thirdloop extending from between the rollers of the two pairs of centrallyconnected links, a plurality of swingletrees having linkand rollerconnections with name to this specification in the presence of the loopsof the draft chain, said bolt and two subscribing Witnesses. slotconnectionsconstituting means to permit the beam to shift incident toshifting I OBIS HOYT' 5 the draft from one portion of the draftWitnesses:
